STS-106 was a space shuttle mission that took place in September 2000. The primary objective was to deliver supplies and equipment to the International Space Station (ISS). The mission involved the shuttle Atlantis, which carried a crew of six astronauts. During the mission, the crew conducted a series of tasks, including installing and activating systems on the ISS. They also transferred cargo and prepared the station for future missions. STS-106 was significant as it helped lay the groundwork for the ISS's continued assembly and operation in low Earth orbit.
